Encountered a larger problem when taking apart my carb for the second time and believed it deserved its own thread to try and figure out what to do with this thing.
Okay so I did some tearing apart, cleaning, and investigating of these minikuni carbs. From what I found these carbs seem to be completely stock when comparing them to the pictures 5twins posted. And you all were right about idle circuit being most likely dirty, there was some dirt in the circuit that I believe caused the idling issue.
Here are the Idle jets

Main jets (too worn out to see the marking but I believe they are stock)

Before I put this thing back together I was thinking about re-jetting this carb with this kit for the BS34's https://www.mikesxs.net/parts/yamaha-xs650-dyno-tune-needle-jet-kit-for-bs-34 from MikesXS and wondering if it they are worth it since this kit says it helps with aftermarket filters and exhaust which I have on this bike.

and while taking them apart I stumbled upon a problem I tried to solve before I took them apart for this second time. The problem being that one of the posts that holds the float in place had sheered off which you can see here.

I have tried and used JB wield to put it back together and and thought it would work but it has not survived the gas and fell apart when I opened up the carbs. Any of you experts out there have a solution for this problem or some compound that will withstand gas better than JB wield does?
